Abstract (en)

A multi purpose screw press (1) is disclosed for separating materials with a composition of liquid and solid matter into a substantially solid part and a substantially liquid part. The cross-sectional diameter of at least a section of the shaft (12) of the screw is substantially increasing in the longitudinal direction from the feeder to a solid matter outlet end (6) of the cylinder, and the press has means for changing the mutual longitudinal position of the solid matter outlet end of the cylindrical portion and the section of the screw conveyor where the cross-sectional diameter of the shaft (12) is substantially increasing, thereby changing the area between the shaft and the solid matter outlet (6) and thus the total compression of the substance.
